Theme star rating different between theme view and review forum view.

[StevenDufresne]

Describe the bug
I've opened this here but the fix may be in the support forums. We round the ratings differently between the theme and the forums.

Looking at https://wordpress.org/themes/twentytwentyfour/:

When viewing the ratings in the theme, the rating is 4/5 stars.
When viewing the ratings in the review forums, the rating is 3.8/5 stars.

The displayed rating on themes rounds to the half- so you get 3.5, 4, 4.5, etc. In this case the 3.8 value is rounded to 4. Which is nice for 3.8, but if it was 3.7 it would round to 3.5; might be less nice for the author.

It looks like this is how it was in the old theme too:

That said, I think the value should be the "real" unrounded value (like support forums). A quick scan of ratings (amazon, google, random other sites) shows an unrounded value even though the star-icons are fixed full or half-intervals, so I think that's expected.
